This beautiful Nightjar was very common indeed at Hat 

 Sanuk in S.W, Siam. It seems mostly to affect hilly 

 countr}^ and most certainly occurs along the whole western 

 border. In south-eastern Siam it has also been collected at 

 Klong Yai, but it appears to be rather rare in those parts of 

 the country.
